In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

This study was based on measurements of growth and shape of 50 clones of wild cherry, Prunus avium L, in south Sweden and aimed at finding out wether or not any of these clones are useful for commercial propagation. Initially, a short assembly of documented knowledge concerning wild cherry as a timber producing tree species was put together. The study of the 50 clones includes information gathered during the fall of 2006 from four trials located in the counties of Blekinge, Småland and Västergöland. The oldest trial, founded in Tranemåla, Blekinge, in 1992, was focused on offspring and aimed at discerning differences between provenances and at developing an Adapted plant material. The other experiments were both clone trials and founded in 2002. These are based on 50 individuals selected from the offspring trial in Tranemåla.

Today there is a research project undertaken by the Swedish University of Agricultural Sciences along with Wången (a highschool specialized in trotter training), which focuses on trotting horse training, performance and health. The project investigates how exercise intensity and feeding strategies affect the development of growing horses. The project includes two groups of horses where all 16 horses are fed in the same way. One group of eight individuals are trained 100% compared to conventional training and the other group are trained 20% less than the other group. All horses are trained twice a week and are out at pasture beyond that.

This study was conducted in the Master program at The Music Pedagogical Center (MPC) at The Royal College of Music in Stockholm. Korta musikresor (Short Music Journeys) is the Swedish term used for a receptive method of music therapy Adapted from the tradition of The Bonny Method of Guided Imagery and Music (BMGIM) and the theory and practice of Expressive Arts Therapy. The KMR method uses carefully selected short pieces of music, lasting between 2 and 5 minutes, to work on various psychological problems and life- crises. The music session is conducted in a slightly altered state of consciousness with a clear focus being established beforehand in a verbal dialogue with the psychotherapist. There is also the possibility of using artwork to process and explore the imagery after the music listening.

AbstractThis is a thesis done in cooperation with the firm Somas and University of Karlstad. The project is an independent final examination part of the program in Innovation and DesignEngineering comprising 22.5 points, and performed by Mia Myrén Zreloff during spring term 2012. In parallel and collaboration, Fredrik Kjellin performs a similar job for the same company and with the same extent, but for the Program in Mechanical Engineering.The client and supervisor at the company have been Magnus Jansson and Anders Josefsson. At Karlstad University has technical supervisor been Hans Johansson, and in the design- and development process it was Monica Jakobsson. Examiner has been Fredrik Thuvander, professor in the Faculty of Technology and Science at Karlstad University.The mission has been to make a basis work for the company's own development and make a computational model to calculate, visualize and implement materials and other solutions in the manufacture of the company's ball valves.The project has undergone three major phases that included thorough study of the company, production, the problem and product.

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks Adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter  in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.

The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.

Purpose: Reading aloud to children and having a conversation about a book, which is read to them, has attracted much attention as important factors that influence children's language development. Language development for children is one of the most important tasks that the preschool- teachers have, and according to ?Läroplanet?, all children must have the opportunity to develop their language. The aim of this study was to examine how reading aloud, and by letting them speak about a certain book, ?boksamtal? impacts preschool-children`s ability to develop their language according to preschool- teachers.Method: I have used a qualitative method by interviewing four preschool- teachers.

The consumption and energy use in today's society contributes to the on-going climate change that creates a debt of life quality for future generations (www, DN, 2007, a). The resources that are used by humans exceed by far what is sustainable (www, Regeringen, 2007, a). The purpose of this paper is to examine how a message about energy conservation should be designed to reach youths. This will be attempted by showing their thoughts on energy and environmental issues and also what it would take for them to get more involved in these issues. The views of the youths are gained by a number of focus group-interviews, which where carried out in the fall of 2007, with kids in the ages 12 to 19. Apart from these interviews, interviews where also conducted with representatives from different youth organisations in Sweden, which gave their views on how to get a message across to kids.

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.

Variation in tuber quality within a single field was one of the motives for a pilot study in Halland, in south-western Sweden conducted during 2002. Quality problems in potatoes have been increasing due to the aggregation of several small fields with different land use history into larger farm units, which are heterogeneous in soil properties and fertility. The study in Halland indicated that both the uniformity and the mean size of tubers may increase from site-specific K fertilization, whereas total yields may be unaffected. The results from this pilot-study with site-specific fertilization showed that tubers reached a more uniform quality and gave a more uniform mean size, while the total yield wasn't affected at all. Site-specific K-fertilization has been applied for some years in Halland with good results. The aim of this study was to test this technique in another potato growing area.

This study is predominantly qualitative. It is also descriptive to a large extent and notoriented towards hypothesis-testing. The study aims at studying what has influenceddigitization of old Swedish dramatical works through the Dramawebben projekt, whilefocusing on the technical solutions. Four different data collection methods have been applied.Interviews and a questionaire with open-ended questions were the two primary tools. Adocument analysis and observations were applied as well.Examples from earlier research to relate to questions about digitization as an institutional andsocietal practice are presented.

More and more companies open up facilities and stores in countries all around the world. Entering a new country means a new culture, a new language, different norms and values and new people with a different way of thinking unlike what you are used to. In order to survive and be successful in this new country means that you have to adapt to the new culture and its components you encounter.The purpose of this thesis has been to identify possibilities and barriers in the Middle Eastern culture affecting international clothing companies. Furthermore it has been investigated how these companies must adapt their products and promotion to this culture.In order to obtain relevant data for achieving the purpose of the study interviews and observations was made at three international clothing companies in Tehran, Iran. These were Mango, United Colors of Benetton and adidas.
